Heated bed improvements and electronics cooling

The issues with ABS printing on Mooz 2 is the printing temperature of the heated bed, the thermal expansion of the plastic glued on the heating element is not even resulting in surface waves as shown in the video below.

Last improvement is the cooling for the electronics, many have complained about random resets and the reason is that the steppers controllers are placed in a closed enclosure. Here a lot of heat is generated (i measured 92C inside the plastic cover) and i believe as a minimum we should have on the board some heat sinks, they are not that expensive. I went a bit further and i have also installed a fan.
